Answer :
To find the mass of 6.3 moles of a substance with a molar mass of 98.2 grams per mole, you can follow these steps:
1. Understand the formula: The relationship between mass, moles, and molar mass is given by the formula:
[tex]\[
\text{mass} = \text{moles} \times \text{molar mass}
\][/tex]
2. Identify the values:
- Molar mass = 98.2 g/mol
- Moles = 6.3 mol
3. Substitute the values into the formula:
[tex]\[
\text{mass} = 6.3 \, \text{mol} \times 98.2 \, \text{g/mol}
\][/tex]
4. Calculate the mass:
- Multiply the number of moles by the molar mass to find the mass:
[tex]\[
\text{mass} = 6.3 \times 98.2 = 618.66 \, \text{grams}
\][/tex]
Therefore, the mass of 6.3 moles of the substance is approximately 618.66 grams. Looking at the provided options, none of them exactly match this result. However, since option "d. [tex]$6.2 \times 10^2 g$[/tex]" is closest to 618.66 grams (since [tex]\(6.2 \times 10^2\)[/tex] is 620 grams), it is the best match.
